DATA ACCESS REGISTER
General Description
The F407 Data Access Register (DAR) performs memory address arithmetic for RAM resident
stack applications. It contains three 4-bit registers intended for Program Counter (R0),
Stack Pointer (R1), and Operand Address (R2). The F407 implements 16 instructions which
allow either pre- or post-decrement/increment and register-to-register transfer in a
single clock cycle. It is expandable in 4-bit increments and can operate at a 30 MHZ
microinstruction rate on a 16-bit word. The TRI-STATE outputs are provided for
bus-oriented applications. The F407 is fully compatible with all TTL families.
